A moisture barrier is molded and/or glued around an exposed section of a conductor where a surrounding insulation layer is removed. A gap between the conductor and a surrounding insulation layer consequently terminates at the moisture barrier and moisture is prevented from creeping any further. The moisture barrier is preferably integrated in a wick dam of a test cord utilized in a telephone line-testing device.

1. A moisture barrier for preventing moisture from propagating beyond a gap between a core and a surrounding layer, said moisture barrier comprising a molded housing snuggly encompassing an exposed core section where said surrounding layer is removed, further comprising a first crimping means fixedly crimped on said surrounding layer next to said exposed core section such that a first force externally applied on said insulation layer is transmitted via said crimping means onto said molded housing.2. A moisture barrier for preventing moisture from propagating beyond a gap between a core and a surrounding layer, said moisture barrier comprising a molded housing snuggly encompassing an exposed core section where said surrounding layer is removed, further comprising a second crimping means fixedly crimped on an additional insulation layer next to said exposed core section and opposing said surrounding layer such that a second force externally applied on said core layer is transmitted via said additional insulation layer and said second crimping means onto said molded housing.3. A moisture barrier for preventing moisture from propagating along a gap between a core and a surrounding layer, said moisture barrier comprising:a. two crimping means fixedly crimped on said surrounding layer next to an exposed core section along which said surrounding layer is removed such that a first force externally applied on said insulation layer is transmitted via a first of said two crimping means onto said molded housing and such that a second force externally applied on said core layer is transmitted via a second of said two crimping means onto said molded housing; and b. a molded housing snuggly holding said exposed core section and said two crimping means such that said exposed core section is strain relieved via said two crimping means and said molded housing. 4. The moisture barrier of claim 3, wherein said core includes an electrical conductor and said surrounding layer includes an electrical insulator.5. The moisture barrier of claim 4, wherein said core further includes a core layer surrounding said conductor.6. The moisture barrier of claim 3, wherein said molded housing is a wick dam configured for fitting into a correspondingly shaped portion of a device housing such that one end of said conductor terminates inside said device housing and such that the other end of said conductor terminates outside said device housing.7. The moisture barrier of claim 6, wherein said moisture barrier, said conductor and said wick dam are part of an electric test cord.8. The moisture barrier of claim 7, wherein said device housing is part of an electrical testing device.9. A test cord comprising:a. an electrical conductor configured for transmitting a voltage from a peripheral contact to an electrical terminal of an electrical device; b. an insulator layer surrounding said conductor between said peripheral contact and one end of an exposed core section; c. a molded housing snuggly encompassing said exposed core section such that a gap between said conductor and said insulator layer terminates at said molded housing and such that moisture eventually present in said gap is prevented from propagating beyond said gap towards said terminal; and wherein said molded housing is part of a wick dam that snuggly seals a correspondingly shaped opening of said electrical device. 10. The test cord of claim 9, further comprising two crimping means fixedly crimped on said surrounding layer next to said exposed core such that a first force externally applied on said insulation layer is transmitted via a first of said two crimping means onto said molded housing and such that a second force externally applied on said core layer is transmitted via a second of said two crimping means onto said molded housing.11. The test cord of claim 9, wherein said device housing is part of an electrical testing device.12. An electrical testing device comprising:a. a device housing having an opening for accessing internal terminals; b. a test cord comprising: i. an electrical conductor configured for transmitting a voltage from a peripheral contact to an electrical terminal of an electrical device; ii. an insulator layer surrounding said conductor between said peripheral contact and one end of an exposed core section; and iii. a wick dam snuggly encompassing said exposed core section such that a gap between said conductor and said insulator layer terminates at said molded housing and such that moisture eventually present in said gap is prevented from propagating beyond said gap towards said terminal, wherein said wick dam has an outside shape that is snuggly held in said opening. 13. The testing device of claim 12 being a telephone line-testing device.14. The electrical testing device of claim 12, further comprising two crimping means fixedly crimped on said surrounding layer next to said exposed core such that a first force externally applied on said insulation layer is transmitted via a first of said two crimping means onto said molded housing and such that a second force externally applied on said core layer is transmitted via a second of said two crimping means onto said molded housing.
